Collecting Canal Maintenance: Initial Study/Proposed Mitigated Negative Declaration


The Division of Flood Management proposes to conduct the Collecting Canal Maintenance of Project No. 6 (c). These facilities, which are part of the Sacramento River Flood Control Project, are maintained in order to minimize flood risk.  Maintenance activities would include:

  • sediment removal from approximately 60 miles of collecting canals;
  • bridge repair and maintenance of three bridges (CC-2, CC-4, EL-1A);
  • culvert repair, replacement, or removal; and
  • debris removal, woody vegetation removal, or vegetation spraying associated with these activities.

These facilities are located between the Sutter Buttes (south of Colusa) and Nicolaus (north of Sacramento).
